The National Weather Service downgraded Rachel to post-tropical status as it transitioned inland across the desert southwest following a weekend of impacts to southern California. The system had generated significant flooding and coastal damage before moving northeast through the region.
Coastal communities faced continued threats from the storm’s remnants throughout the weekend. Oceanfront properties in Long Beach, Newport Beach, and other California coastal cities experienced partial submersion as heavy surf overwhelmed protective sand barriers. Flood warnings remained in effect along much of the California coastline from San Diego northward to the San Francisco Bay area. High surf conditions were expected to persist, and weather officials warned of ongoing flash flood risks as the system continued to produce rain and wind gusts across a wide area.
As Rachel pushed inland and northward, secondary impacts included rockslides that temporarily blocked roads in affected areas. Las Vegas received significant rainfall that set a new daily record, while the National Weather Service issued flood watches for much of Utah, with Salt Lake City anticipated to receive heavy precipitation beginning later in the day.
Weather forecasters characterized Rachel as potentially a precursor to more severe conditions ahead. Meteorological models indicate that an exceptionally strong El Niño weather pattern is expected to develop over the coming months, which would typically bring warmer-than-average ocean temperatures and associated hazards including potential record rainfall, dangerous surf, and mudslides extending into the following year. California officials have responded by pre-positioning emergency supplies and resources, including millions of sandbags and portable flood barriers, while conducting infrastructure inspections and reinforcement work.
The strong weather pattern is also expected to affect Mexico, where Hurricane Simon was impacting the Pacific Coast as a Category 4 system, moving parallel to the shoreline near Manzanillo approximately 60 miles offshore. Mexican officials warned of potential severe damage from the hurricane’s winds and rainfall regardless of whether landfall occurs.
